The thesis focuses on three specific challenges for the seafood industry: (1) the quality and capacity of national institutions; (2) the importance of environmental factors for aquaculture production; and (3) how to monitor and, hopefully, manage fisheries with few and uncertain observations (data-poor fisheries). Each challenge has been studied empirically using proper methodologies and presented ...

<p>The research presented in this thesis has focused on the economic valuation of climate change impacts on ecotourism in a coastal wetland using three different methods of stated-preference techniques to provide answers to different research questions related to coastal tourism and climate change. Rekawa coastal wetland in Southern Sri Lanka was taken as the empirical context to examine the identified ...

Barents Sea ecosystem is limited. Due to the information available on benthos the Ecopath model of Sørfjord, Northern Norway, was used to investigate possible trophic changes with introduction of king crab to the model. A literature study of the king crab was conducted to find information on diet, mortality, consumption rate and other life history parameters required by the model. A short ...

Changing climate is expected to alter precipitation patterns in the Arctic, with consequences for subsurface temperature and moisture conditions, community structure, and nutrient mobilization through microbial belowground processes. Here, we address the effect of increased snow depth on the variation in species richness and community structure ...

Every year, almost 2 billion new vehicle tires are produced world-wide. At the same time >1 billion tires reach their end of life. During use, tire wear particles (TWPs) form through abrasion of the rubber material, and in contact with the road surface composites of both materials form tire and road wear particles (TRWPs). These emissions represent a large fraction of total microplastic pollution, ...

Aquaculture worldwide is under constant scrutiny and financial pressure to maintain fish health, while providing an essential food source to a growing populace. To assist in monitoring mariculture sites and preventing harmful diseases, we tested a recently proposed method of trace pathogen detection using eDNA metabarcoding. The target pathogen, Paramoeba perurans, is the etiological agent of AGD, ...

Three experiments were performed during spring 2004, to develop a method to elevate the blood plasma level of 11-ketotestosterone (11-KT) in male brood stock of spotted wolffish Anarhichas minor, and to study the effects of 11-KT on sperm production. Intraperitoneal implantation of silastic capsules containing 11-KT - coconut butter mixture and 11-KT - sesame oil mixture and intramuscular injection ...
